Logout, Shutdown, etc screen issue

[Fintan]

Hi, after installing 18.10 I have a completely washed out, almost white log out, etc. back ground/splash screen and can hardly see any icons or text.
Where can I change the back ground/splash. Looked in system settings but didn'r find anything there.

Cheers
Fred

The setting is in Startup and Shutdown, Login Screen (SDDM), Breeze theme, click the background frame. But that's not the problem, Kubuntu comes with only one SDDM theme, Breeze, and it is set up with a !@#$ awful, cretinous, extreme blurring of the image, which you aptly report as completely washed out.

You could try getting a new theme. My results with KDE DLC are usually poor, so I haven't tried "Get New Theme" here.

But I've hacked the supplied theme to turn off the blur, I found on reddit: How to un-blur the background in login and lock screen in Plasma 5.13.x?. Edit the file /usr/share/sddm/themes/breeze/Main.qml, find the lines

   WallpaperFader {
       visible: config.type == "image"

and change the second to "visible: false". Quickly test it with
sddm-greeter --test-mode --theme /usr/share/sddm/themes/breeze.

Of course, editing a system file... warning, here be dragons, and an update might overwrite the change. In fact, an update should overwrite this ... this ... I should breathe deeply and calm down. Maybe cloning the theme would be a good idea.

Leave / logout screen background ?

Do you mean the screen which is displayed when you click the 'Leave' button ?



There is no setting. As default, the plasma 5.13 & 5.14 & Breeze LnF, are using darkened rectangle to hide the desktop:

Rectangle {
id: backgroundRect
anchors.fill: parent
//use "black" because this is intended to look like a general darkening of the scene. a dark gray as normal background would just look too "washed out"
color: root.isLightColor(PlasmaCore.ColorScope.backgroundColor) ? PlasmaCore.ColorScope.backgroundColor : "black"
opacity: 0.5
}

Could you show your wallpaper ?
Your theme ?
Your leave screen ?

There is:

An edited Breeze LnF theme with the image background

Thanks man, unfortunately I really fubared this one. Don't ask, it is too embarrassing.

Anyway could you you please send me your full Main.qml file?

Or do you know of a way to recover the original?

I tried with the 18.04 version. That does NOT work.

Thanks for your efforts and owe you.

Cheers
Fred

Edit: No worries.

Got it back by reinstalling sddm-theme-breeze.

But am still unsure if you mean this:
WallpaperFader {
visible = false

Hi Rog, good to see you are still here Thanks for the input and really like the screen shots you posted. Will try this out over the WE if I can find some time.
Cheers and hope all is well or at least getting slightly better on your side of the pond
